Direct Pin connection keyboard support

[rootexpression]

Is there a way to do direct pin? I didn't find anything other than matrix configuration in the docs, or in my searches (I may have done a bad job of choosing the right keywords, so if I missed something please let me know).

For really compact keyboards and macro pads it'd be much easier to, in some cases, just direct wire them, and help keep it low profile in some instances (by a few mm).

I'd like to see that as an option, if its something that can find its way onto the todo list.

Yes, there is. I don't recall an example but they use a dummy pin as a row and use the individual pins for where the switches are connected. (or vice versa).

By dummy pin, do you mean set a pin that doesn't exist on the board? Like P0.99? Or a pin that exists, but isn't connected?

Not quite. 0 I believe is usually connected to a crystal and will ignore any I/O to it. Or a pic that the chip doesn't have connected to an outside pin on the board. This will depend on the board in question

Excellent info to have. Thank you! I'll have to dig through the schematics of the boards I have and see what I can turn up. I'm betting they all have at least a few pins connected to nothing. I can give that a try when I get something wired up to test with.
